quobyte driver introduced extra dependency to xattr

[Danny Al-Gaaf]

The Quobyte driver introduced an new dependency to xattr python binding. This driver is the only consumer to xattr. During the review of the quobyte nova volume driver this dependency was removed [1] between patchset 18 and 19.

The driver needs to get changed to call a binary (getfattr) and remove the otherwise not needed dependency to xattr as in nova.

    quobyte: remove dependency to xattr

    The Quobyte driver introduced an new dependency to xattr
    python binding. This driver is the only consumer of xattr.

    Instead of introducing new dependencies call getfattr binary
    as already done in the quobyte nova volume driver.
